Detectives are combing through surveillance video from the Aventura Mall, hoping it will lead them to the killer of a Boca Raton woman and her 7-year-old daughter.
Palm Beach County Crime Stoppers received an anonymous call Monday saying a ''suspicious male'' was following a woman and her child who were entering the mall through the first floor west entrance and exit of Nordstrom at 2:41 p.m. April 30, police said.
The caller said the man matched the description of the composite sketch tied to the murders of Nancy Bochicchio, 47, and her daughter Joey, said Officer Sandra Boonenberg, a spokeswoman with the Boca Raton Police Department.
''Detectives drove down there and were able to obtain video of the man following the woman and child inside Nordstrom,'' Boonenberg said Wednesday.
Bochicchio and her daughter were found dead in their SUV on Dec. 12 in the parking lot of the Town Center mall in Boca Raton.
A similar incident occurred Aug. 7 when a woman and her 2-year-old son were left bound and gagged in her SUV.
For several months the sketch has been distributed across South Florida. The sketch depicts a man with his hair pulled back in a ponytail. He wore dark sunglasses and gloves. His face was covered with a floppy hat. He was about five feet six inches tall.
Investigators are pleading with the caller to contact them.
The city of Boca Raton is offering a reward of up to $350,000 leading to an arrest.
Anyone with information about the murders may call Boca Raton police at 561-416-3331 or Palm Beach County Crime Stoppers at 800-458-TIPS (8477).
